In digital TV broadcasting, such as terrestrial, cable, satellite, and IPTV, the head-end of digital TV broadcasting has a more complicated transmission structure than that of analog TV broadcasting. Furthermore, digital TV broadcasting has a feature that supports multiplex models, such as Multiple Program Transport Stream (MPTS). Therefore, the purpose of our work was to design and examine a more efficient new system of emergency alert message transmission to support the digital TV broadcasting environments. Digital TV broadcasting is the IP generation or RF transmission of 8-VSB, QAM, and QPSK modulated through a multiplexer or re-multiplexer multiplexed stream as a MPEG-2 Transport Stream after content encoding. The new system proposed in this paper transmits an emergency alert message without scrambling after replacing the PID and payload of the -packet with the message prototype in the TS stream from the multiplexer. If we need to transmit an emergency alert message under digital TV broadcasting services, then the receiver first checks the PID of each packet in the TS stream for the emergency alert message. Next, if a packet is determined to be an emergency alert message, then the set-top box displays the message on the TV screen using its function of On Screen Display, or the PC based software displays the message on the monitor screen using its function of overlay with user interface if the packet is found to be an emergency alert message. We have designed an emergency alert message protocol and a system model. By experiments and analysis of the system, we concluded that the system achieved efficiency and the ability to send and receive emergency alert messages using the system under different digital TV broadcasting service environments.

Purpose : The purpose of this study was to provide appropriate direction for triage education by investigating the knowledge level of triage in 119 EMTs before and after the triage education. Methods : The questionnaire was filled out by newly assigned 33 EMTs in the fire service academy in I metropolitan city from November 1, 2013. The data were analyzed using SPSS WIN 21.0 program. Results : The lowest knowledge level by 119 triage was the potential emergency related question, but that by case-based triage was the semi-emergency related questions. The knowledge score by case-based triage before education was 51.14 points. This was lower than knowledge score by 119 triage, that is, 75.70 points. After education, the knowledge level by 119 triage was significantly improved(p =.000). However, there was no significant difference in the knowledge level by case-based triage(p =.236). Conclusion : It is necessary to provide systematic and periodic education and training for 119 EMTs toward triage to improve triage accuracy and efficient circulation of the emergency medical service system. Especially, it is very important to provide case-based triage education for field application.

Purpose: As emergency medical service fund is further expanded due to amendment of the law on emergency medical services in 2008, Korean government has prepared to intervene in a comprehensive manner to strengthen a trauma treatment system. As a result, it announced a master plan to establish a serious trauma treatment center in 16 areas across the nation. Therefore, this study has attempted to investigate the current status of the serious trauma treatment centers and suggest the goal and improvement plan of future serious trauma treatment centers. Methods: As of 2011, Korea operates 23 emergency cerebrovascular service centers, 23 emergency heart disease centers and 35 severe trauma treatment centers across the country. 12 emergency medical service centers have been chosen among the serious trauma treatment centers. Then, top six (6) centers chosen at Emergency Medical Institute Assessment 2011 by Ministry of Health and Welfare have been selected, and floor layout and spatial allocation by usage have been reviewed and analyzed. Results: Consequently, this study has investigated the spatial components, circulation layout and spatial allocation of a serious trauma treatment. For construction planning in consideration of the fundamental objectives and goal of emergency medical services, it is essential to allot spaces and select exact spatial components. It appears that it is necessary to design spaces for emergency medical services and come up with construction planning through appropriate spatial allocation.

Emergency medicine(EM) is the specialty of evaluating, stabilizing and initiating treatment for patients with life or limb-threatening illnesses or injuries. Techniques unique to the specialty of EM are the triage systems, quick stabilization methods, and emergency surgery procedures. The field of EM encompasses areas such as emergency department management, disaster planning and management, the management of emergency medical service(EMS) systems, research into such areas as brain and heart resuscitation, trauma and disaster management, survival medicine, and environmental emergencies(cold and heat injuries, poisioning, decompression sickness and barotrauma). Today, in addition to providing emergency care, the emergency specialists have moral and legal obligations to assess and report probable cases of child and spouse abuse, sexual assault, and alcohol and drug abuse. Future, the EM should provide surveillance, identification, intervention, and evaluation of injury and disease, therefore EM will remain as a key component of evolving community health care system.

Purpose: The emergency medical service (EMS) system in Japan is similar to that in Korea. This study reviewed the development of paramedics who are major personnel in the respective EMS system of their country. Methods: We searched law for paramedics and publications in J-stage, MEDLINE and the webpage of Japan's Fire and Disaster Management Agency. Results: Paramedic training had started in Japan in 1991, and most paramedics were employed in fire departments. In Japan, ambulances belonging to fire department are staffed by a three-person unit, including at least one paramedic. Medical control advisory boards were established in all Japanese prefectures in 2003 with the purpose of upgrading the activities of ambulance personnel, including paramedics. The scope of paramedics' work has been widened owing to the continued efforts of medical control advisory boards. This allows them to perform invasive procedures including tracheal intubation, intravenous line placement, and epinephrine administration under medical control of a physician. Conclusion: As paramedics' responsibilities expand, further development of the paramedic role and an effective medical control advisory board system are imperative both Korea and Japan.

Purpose: The purpose of this study is to determine potential differences in pre-hospital cases of cardiac arrest and drug Intoxication between elderly group and non-elderly group on local emergency activity sites of rescue 119 team for those cases, so that it can provide useful reference materials for a system of corresponding emergency medical services. Methods: Patients with cardiac arrest and drug intoxication in the elderly and the non-elderly group were analyzed by analyzing the Ambulance Run Report for 3 years from January 2007 to December 2009. Results: According to analysis on potential differences between elderly and the non-elderly group, it was found that there was no significant difference between elderly cases (evacuated to hospital due to cardiac arrest and drug poisoning) and non-elderly cases in year of onset (p = .247), quarter of onset (p = .813), sex (p = .235), consciousness state (p = .126), place of onset (p = .215) and number of first aid services (applied to emergency cases) respectively, but there were significant differences between elderly cases and non-elderly cases in guardian availability (p = .042), time zone of onset (p = .050), distance from the site of onset (p = .278), type of onset (p = .000), number of first aid services depending on distance of evacuation (p = .008) and effectiveness of emergency care (p = .003) on statistical basis. Conclusion: It is important to establish a system of early emergency case reports for rational emergency case management with lower mortality; shorten distance from the site of onset at each time zone of onset in emergency cases; employ more emergency team members; facilitate firsthand / secondhand medical instructions for emergency teams in specialized emergency care depending on distance of evacuation for each kind of onset (elderly group vs. non-elderly group); and improve rate of resuscitated emergency cases by extending the scope of works for emergency medical technicians into wider applications, so that it will be possible to take timely and appropriate measures for emergency settings of ever-increasing aged population in near future.

VoIP 망에서 긴급통화 서비스는 기존의 유 무선 전화 서비스와 같이 필수 사항이다. 이를 지원하기 위한 표준화 작업이 활발히 진행되고 있으며, National Emergency Number Association (NENA)는 기존의 유 무선망에서의 긴급통화 서비스를 위한 프레임워크 및 프로시져를 개발하고 있다. 반면에 Internet Engineering Task Force (IETF)에서는 착발신이 모두 IP 환경을 고려한 긴급통신 프로토콜에 초점을 두고 있다. 그 결과, 두 모델 간에 불일치가 발생한다. 본 논문에서는 이를 해결하기 위해, NENA 구조를 채택하여 수정하고, 수정된 모델에 IETF 프로토콜을 적용할 수 있는 SIP 기반 VoIP 긴급통화 시스템을 설계하고 구현한다. 특히, 긴급 호를 다루는 재난방재센터 (PSAP, Public Safety Answering Point)는 기존 통신 환경 및 인터넷 환경 모두를 고려한다. 본 시스템은 유닉스 환경에서 구현된다.
